Title: Compensation of Thermal Drift of Temperature Sensitive Circuitry
IPC: H01L27/06
Filed: 1979-10-29
Abstract: Compensation of thermal drift of temperature sensitive circuitry in an integrated circuit is achieved by heating the temperature sensitive circuitry by applying power to a heating element in the integrated circuit, testing the temperature sensitive circuitry, and trimming a thin film compensation resistor in the circuitry in accordance with the testing results. The heating element is an integrated resistor (16) adjacent to or surrounding the temperature sensitive circuitry (12). As the temperature of the temperature sensitive circuitry (12) is increased, testing apparatus is used to measure a temperature sensitive parameter of the temperature sensitive circuitry control signals, indicative of the amount of required trimming of the thin film compensation resistor (19, 20) to compensate the thermal drift of the temperature sensitive circuitry (12). The control signals are utilized to control the operations of a laser which precisely trims the thin film compensating resistor by the required amount. <IMAGE>

Title: Animal feeds and process for the production thereof
IPC: A23K50/30
Filed: 1981-01-29
Abstract: A process is described for converting plant residues and wastes, such as those of labiateae from which essential oils have been extracted by steam distillation and pea and bean haulms, into an animal foodstuff. Plant material, comprising the residues or wastes is subjected to shock-drying to reduce the moisture content in minimum time to a value not above 10% by weight. The dried material is then ground so that 98 to 100% of the material has a size below 2mm., preferably 1mm, and at least 8% of the material has a size above 0.5 mm. The ground material is then sieved and a sieve fraction with a size inthe range of 0.35 to 0.75 mm., depending upon the starting material is separated. The sieve fraction with a grain size below the separated sieve fraction constitutes the desired foodstuff which may be pelletised alone or with other feed components.
